ResultPicker

Result picker was designed to simply yield return value before the block ends My own use case was returning model built inside transaction, which could be rolled back because it was invalid. Normally, solution is

  x = nil
  something do
    stuff
    x = value
    more_stuff
  end
  x

which is ugly. The better idea is to wrap this stuff inside one of your methods e.g. synchronize, transaction, and this class allows you to DRY

Usage:

  ResultPicker.pick! do |result_picker|
    something do
      stuff
      result_picker.call value
      more_stuff
    end
  end
